NVIDIA's recently released GeForce 9800 GTX+ GPU was meant to do battle with ATI's Radeon HD 4850 and we have a fine example here in Zotac's GeForce 9800 GTX+ Zone Edition. Boasting an elaborate water-cooling mechanism, we check to see if the 9800 GTX+ has what it takes to go against the HD 4850 and if Zotac's water-cooling unit actually works.
